Abstract
This disclosure describes an audio video distribution system that uses a local area network to distribute a digital audio signal and that uses multiple network speaker nodes to broadcast the digital audio in a multi speaker session. The system includes a local area network that distributes the digital audio signal for the audio video distribution system. In addition, the system includes a first network speaker node participating in a multi speaker session and performing in a master mode, and where the first network speaker node calculates, originates, and controls a distributed multi session clock that is distributed over the network. The system further includes one or more additional network speaker nodes participating in the multi speaker session and perform in a slave mode, and where the additional network speaker nodes receive the distributed multi session clock from the first speaker node.
